ber. It seems to belong to the subtype PulvinuUna elegans, 

 with its subquadrangular chambers ; and it may be P. Orhignyi 

 or P. caracoUa (Roemer), showing the high umbonate face. 

 Fig. 9, Rotalia cretce^ is a relatively large Planovhulina^ an- 

 swering to Reuss's PI. ammonoides. Fig. 10, Planulina tur- 

 (jidttj and fig. 11, PI. sicida (1838), are Planulince^ near to, if 

 not the same as, PI. ariminensis, with falcate chambers. So 

 also the much larger (fig. 12) PI. ocellaris] but its large scat- 

 tered foramina may, like those in fig. 8, possibly be due to 

 parasitic borings*. 



Figs. 13, PI. ampla^ and 14, PI. angusta^ are thick-margined 

 and strongly septated, with triangular and oblong segments, 

 as in fig. 8, and may be flat -face views of Pidvinulma cara- 

 colla, P. ornata, or some other of the P. elegans group. (See 

 Phil. Trans, vol. civ. p. 390 &c.) Fig. 15, Planulina sjpatiosa^ 

 a young form of PI. spatiosa^ Ehr, (from the tripoli-shale of 

 Oran, Africa), Monatsb. 1844, pp. 67 & 94, and ' Mikrogeol.' 

 pi. xxi. fig. 95, is a variety of PulvinuUna repanda^ near var. 

 pulchella. 



Fig. 16, Textilaria sulcata (" Text, striata^ 1838 ") may 

 well pass as T. striata^ Ehr. Figs, 17 j «, ^, Text, glohulosa 

 (1838), is the common minute (arrested) form of T. gihbosa. 

 Figs. 18, a, h, Text, linearis (" T. acicidata^ 1838 ; see 8tro2jho- 

 vonus ") is Bolivina punctata. As all Ehrenberg's Strojiilioconi 

 are either Bolivime or closely allied VirguUnce, the allusion to 

 ■Strojyhoconus here might have been carried further with justice 

 to our author's perspicacity. Fig, 19, Text, dilatata (1838), is 

 a good T. gihbosa. Figs. 20, a, h, Text, aculeata^ are separa- 

 ble, — 20 a as a coarse aculeate Text, gihhosa^ and 20 h as a 

 thick-shelled variety oi Bolivina punctata^ bluntly aculeate on 

 the outer margin of each chamber, and as such might be 

 registered as B. aculeata] whilst the Textilaria falls to T. 

 suba7igulata, D'Orb., 1846. Fig. 21 a, Text. 2}(ichi/aulax 

 ("compare T. brevis^^), and fig, 21 &, T. sulcata^ come under 

 T. striata, Ehr. 



Fig. 22, Grammostomum polystigma, is either a young spe- 

 cimen or the early chambers of a very broad strong-shelled 

 Bolivina dilatata.^ Reuss, with short but transversely broad 

 and falcate chambers ; 23, Gr. dilatatum^ is also a thick- 

 shelled Bolivina dilatata, but with less curved and more 

 quadrangular chambers; 24, Gr.pinnula, is a common Texti- 

 laria of the gihbosa type, with a smooth and evenly tapering 

 subarcuate shell ; 25, Gr. convergens, is probably a long-ovate 

 well-grown Bolivina punctata (?), but without visible pores; 



* In specimens from the Chalk of Meudon there are frequent borings 

 (figs. 20, 37, & 38 of pi. xxvii.).
